Wattle Point Wind Farm

A few kilometres south-west of Edithburgh, the skyline fills with the slow, hypnotic sweep of Wattle Point Wind Farm. When it began operating in April 2005 it was among the largest wind farms in Australia, and its 55 turbines remain an arresting sight: each tower stands 67 metres high, and with a 40-metre blade at the top of its arc the tip reaches around 110 metres above the paddocks.

There's a free public viewing area with interpretive displays, where you can stand almost beneath a working turbine and listen to the strange, soft whoosh of the blades. Kids tend to be transfixed; photographers come for the rows of white towers marching toward the sea. The farm generates enough electricity to power tens of thousands of homes, and it has become as much a part of the lower Yorke landscape as the salt lakes and the long jetties.

Pair the stop with the nearby Troubridge Hill Lighthouse and the coastal route around to Sultana Point for an easy half-day loop out of Edithburgh.
